BIOHYBRID MATERIALS AS PROMISING BIOCATALYSTS IN THE DEVELOPMENT OF BIOFILTERS FOR THE METHANOL WASTEWATER TREATMENT

Abstract

Yeast cells were immobilized in a matrix made of tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) by one-step sol-gel route of synthesis in the presence of polyethylene glycol (PEG) or polyvinyl alcohol (PVA). . A trickling biofilter with and without active aeration was designed using entrapped yeast cells to treat methanol polluted wastewater.
